Description

Technical Field

[0001] The utility model relates to an automated silkworm breeding technology, in particular to a silkworm foil stacking device. Background Art

[0002] my country has a long history of silk culture and silkworm breeding. At present, silkworm breeding is still mainly operated by manual operation, supplemented by mechanical operation, which is difficult to adapt to the development of modern agriculture. It is urgent to improve the mechanization and automation level of silkworm breeding. At the same time, silkworm breeding is showing a trend of large-scale operation, which requires equipment with a higher degree of mechanization and automation, changing the labor-intensive production mode, reducing labor intensity, improving production and management efficiency, realizing industrial transformation and upgrading, and promoting high-quality development of the industry.

[0003] A fully automatic silkworm raising robot system for mulberry feeding CN2023118298372 and a fully automatic silkworm raising machine CN2021223431549 use a six-axis manipulator to stack silkworm foil. The six-axis manipulator has six degrees of freedom, but the silkworm foil stacking operation does not require so many degrees of freedom, so a two-degree-of-freedom special stacking device is more suitable for silkworm raising and stacking silkworm foil; at the same time, the stacked silkworm foil needs to be manually transferred, specifically, the piles of silkworm foil to be raised need to be manually transferred to the equipment station, and the piles of silkworm foil that have been raised need to be manually transferred from the equipment station to the silkworm room; in addition, both patents are for mulberry leaf silkworm raising, and do not involve feed silkworm raising.

[0004] Silkworm feeding and transmission platform CN2019201033689, this patent is an early application of the inventor, which proposes horizontal conveying of silkworm foil and silkworm feeding operation during the movement of silkworm foil. This equipment requires manual silkworm foil stacking operation, and the degree of automation is low.

[0005] Silkworm foil is a tool for raising silkworms. After long-term use, the silkworm foil will be deformed, resulting in an irregular shape, making it difficult for the robot to use the deformed silkworm foil. In order to control costs, the lifting mechanism will not use high-precision equipment. Therefore, the clamping robot has a certain position deviation during the up and down movement. As a result, when clamping the silkworm foil, some of the silkworm foil cannot enter the clamping groove of the clamping unit, which makes the clamping robot unable to clamp the silkworm foil stably and effectively. In severe cases, the silkworm foil will be squeezed and damaged. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1 and Figure 2As shown, a silkworm foil stacking device includes a rotating mechanism and a lifting mechanism. The lifting mechanism is installed on the rotating mechanism, and the lifting mechanism can be lifted and lowered relative to the rotating mechanism. A cantilever beam 214 is installed on the lifting mechanism, and a silkworm foil clamping assembly 200 is installed on the cantilever beam 214. In this embodiment, the silkworm foil stacking device has a stacking station and a releasing station. When the rotating mechanism is working, the cantilever beam 214 drives the silkworm foil clamping assembly 200 to switch between the stacking station and the releasing station, and the lifting mechanism realizes the lifting and lowering of the silkworm foil clamping assembly 200, thereby facilitating the stacking and releasing of the silkworm foil. Specifically, when it is necessary to feed the silkworm foil, the rotating mechanism drives the cantilever beam 214 to rotate, thereby making the silkworm foil clamping assembly 200 located above the stacking station, and then the lifting mechanism descends, so that the silkworm foil clamping assembly 200 reaches the clamping station, and then the silkworm foil clamping assembly 200 clamps the silkworm foil, and then the lifting mechanism ascends, so that the silkworm foil is separated from the stacking station. The silkworm foil is then released to the release position, and the lifting mechanism is then moved downward. After reaching the designated position, the silkworm foil clamping assembly 200 releases the silkworm foil, allowing the silkworm foil to enter the release position. The above-mentioned action is then repeated to achieve the next silkworm foil station conversion. The stacking device can also be used to stack the silkworm foil after feeding. Specifically, after the silkworm foil after feeding reaches the grabbing position, the lifting mechanism moves downward, causing the silkworm foil clamping assembly 200 to move downward. After reaching the designated position, the silkworm foil clamping assembly 200 clamps the silkworm foil, and the lifting mechanism moves upward to separate the silkworm foil from the grabbing position. The rotating mechanism rotates to drive the silkworm foil clamping assembly 200 to be located at the stacking position. The lifting mechanism moves downward, causing the silkworm foil clamping assembly 200 to move downward. When the silkworm foil clamping assembly 200 reaches the designated position, the silkworm foil clamping assembly 200 releases the silkworm foil, and places the silkworm foil on the stacking position.

[0038] In this embodiment, if Figure 5 and Figure 6 As shown, the silkworm foil clamping assembly 200 includes a mounting frame 121 and a clamping unit 100, and two clamping units 100 are slidably mounted on both ends of the mounting frame 121. Preferably, the mounting frame 121 is a flat plate, and screw holes are provided on the mounting frame 121 to facilitate the installation of the mounting frame 121 and the manipulator. The manipulator is a prior art, and a multi-axis manipulator can be selected according to needs. In this embodiment, the two clamping units 100 are arranged at intervals. In the initial state of the clamping units 100, the spacing between the two clamping units 100 is greater than the width of the silkworm foil, so as to facilitate the clamping of the silkworm foil. Furthermore, a driving mechanism for driving the two clamping units 100 to move toward or away from each other is also installed on the mounting frame 121. When the driving mechanism is working, it drives the two clamping units 100 to move toward or away from each other, so that the two clamping units 100 clamp the silkworm foil or release the silkworm foil.

[0039] In this embodiment, if Fig. 9 As shown, the clamping unit 100 includes a support arm 102, on which a linear guide mechanism is installed. The execution end of the linear guide mechanism is connected to a lifting arm 103, and the execution end of the linear guide mechanism is in a downstroke under the action of the gravity of the lifting arm 103. Both ends of the lifting arm 103 are installed with clamping mechanisms, and the clamping mechanism has a clamping groove, and the entrance of the clamping groove is a bell mouth. Through the bell mouth, the clamping mechanism can use silk foils of different sizes, especially after the silk foil has been used for a period of time and is deformed, it can still enter the clamping groove through the bell mouth and be clamped by the clamping mechanism.

[0040] After the silkworm foil has been used for a period of time, although the silkworm foil is deformed, the structural strength of the four corners of the silkworm foil is relatively high. Under normal circumstances, the four corners of the silkworm foil will not be deformed too much, while the middle area of ​​the silkworm foil will have a more obvious arch or downward bend. In the process of clamping the silkworm foil, the middle sides of the side of the silkworm foil are mainly clamped, and the arched or downward-bent silkworm foil will affect the clamping of the silkworm foil by the clamping mechanism. In addition, in order to save costs, the lifting mechanism is not a high-precision lifting mechanism. Therefore, when the lifting mechanism drives the silkworm foil clamping assembly 200 to lift, there will be a certain position deviation, which will also affect the clamping of the silkworm foil. In this embodiment, if Fig. 9As shown, the clamping mechanism includes a guide piece 108 and a lifting piece 107, and the lifting piece 107 and the guide piece 108 are both installed on the lifting arm 103, the guide piece 108 is located above the lifting piece 107, and a clamping groove is formed between the guide piece 108 and the lifting piece 107, and an upwardly inclined first guide slope 109 is arranged at one end of the guide piece 108 away from the lifting arm 103, and a downwardly inclined second guide slope 110 is arranged at one end of the lifting piece 107 away from the lifting arm 103, and the first guide slope 109 and the second guide slope 110 form a bell mouth. When the clamping mechanism clamps the silkworm foil, when the second guide slope 110 is inserted into the bottom of the silkworm foil, the silkworm foil enters the clamping groove under the guidance of the second guide slope 110, and is then clamped by the clamping groove. When the clamping mechanism clamps the silkworm foil, the silkworm foil is deformed, resulting in irregular After adjustment, if the first guide slope 109 contacts the silkworm foil, as the clamping mechanisms of the two clamping units 100 gradually move closer to the silkworm foil, the silkworm foil applies an upward thrust to the lifting arm 103 through the first guide slope 109, thereby causing the linear guide mechanism to move upward, thereby causing the clamping mechanism to move upward, thereby causing the clamping groove to be aligned with the silkworm foil, and finally clamping the silkworm foil. Therefore, a trumpet mouth is formed by the first guide slope 109 and the second guide slope 110, and the deformed silkworm foil can still enter the clamping groove, and the trumpet mouth can also compensate for the position deviation of the clamping unit 100 caused by the accuracy problem of the lifting mechanism, thereby ensuring that the silkworm foil can enter the clamping groove, and through the linear guide mechanism, the horizontal height of the clamping groove can be adjusted according to the actual situation of the silkworm foil, thereby ensuring the reliability of the silkworm foil clamping.

[0041] In this embodiment, if Fig. 9 As shown, there are two support arms 102, and the ends of the two support arms 102 close to the linear guide mechanism are connected by a connecting rod 106, and the ends of the two support arms 102 away from the linear guide mechanism are connected by a mounting plate. The support arms 102 are cantilevers. After the two support arms 102 are connected by the connecting rod 106 and the mounting plate, the structural strength of the support arms 102 can be increased, thereby increasing the carrying capacity of the silkworm foil clamping unit 100.

[0042] In this embodiment, if Fig. 9As shown, the lifting piece 107 includes an installation section, a vertical section and a horizontal support platform 111. The installation section, the vertical section and the support platform 111 are distributed in a Z shape, and the second guide slope 110 is connected to the support platform 111. To facilitate the processing and installation of the clamping mechanism, the lifting piece 107 is located on one side of the guide piece 108, and the lifting piece 107 and the guide piece 108 are both connected to the support arm 102 through locking screws. Therefore, the lifting piece 107 and the guide piece 108 can be made separately. When the lifting piece 107 and the guide piece 108 are both installed on the support arm 102, on the axial projection plane, a clamping groove is formed between the straight end of the guide piece 108 and the support platform 111, and a bell mouth is formed between the first guide slope 109 and the second guide slope 110.

[0043] In this embodiment, if Fig. 9 The linear guide mechanism includes a linear bearing 104 and a guide rod 105. The linear bearing 104 is installed on the support arm 102, and the guide rod 105 is slidably installed in the linear bearing 104. A limiting cap 112 is provided on the top of the guide rod 105 to prevent the guide rod 105 from falling out of the linear bearing 104. The bottom of the guide rod 105 is connected to the lifting arm 103. Furthermore, the limiting cap 112 is a sheet-mounted structure, and the limiting cap 112 is installed on the top of the guide rod 105 by a locking screw. In the initial state, the guide rod 105 is in a downstroke under the gravity of the lifting arm 103, that is, the limiting cap 112 abuts against the top of the linear bearing 104, and when the guide rod 105 is subjected to an axial upward force, the guide rod 105 moves upward along the linear bearing 104.

[0044] In this embodiment, if Fig. 9 As shown, the guide rod 105 and the lifting arm 103 are detachably connected via a locking screw. Furthermore, a stepped through hole is provided on the lifting arm 103, and the bottom of the guide rod 105 is fitted and installed in the large hole of the stepped through hole. A threaded hole is provided at the bottom of the guide rod 105, and the guide rod 105 and the lifting arm 103 are connected and locked by the locking screw. Therefore, the guide rod 105 and the lifting arm 103 can be quickly disassembled and assembled, which is convenient for the assembly of the silkworm foil clamping unit 100.

[0045] In this embodiment, if Figure 5 and Fig. 9As shown, the clamping unit 100 also includes a sliding plate 101, one end of the support arm 102 close to the mounting frame 121 is connected to the sliding plate 101, and the sliding plate 101 is slidably mounted on the bottom of the mounting frame 121 through a linear motion pair, the linear motion pair belongs to the prior art, and optionally, as shown in the figure, the linear motion pair includes a linear slide rail 127 and a slider 128, the slider 128 is mounted on the sliding plate 101, the linear slide rail 127 is mounted on the mounting frame 121, and the linear slide rail 127 is arranged along the telescopic direction of the clamping unit 100, the slide rail is mounted on the mounting frame 121, and a slide groove is installed on the slider 128, and the slider 128 is provided with a slide groove. 8 is installed on the clamping unit 100, and the slide groove is slidably matched on the linear slide rail 127. In this embodiment, after the silkworm foil is grabbed, it is necessary to move the silkworm foil to a specified position, so the silkworm foil is usually located at the bottom. Therefore, in order to ensure the reliability of the connection between the slider 128 and the linear slide rail 127, the slide groove is optionally a dovetail groove. Of course, the structure of the linear slide rail 127 must also be adapted according to the dovetail groove, thereby ensuring the sliding fit between the linear slide rail 127 and the dovetail groove. Furthermore, in this embodiment, there are two groups of linear moving pairs, which are arranged at intervals. Through the two groups of linear moving pairs, the straightness of the movement of the clamping unit 100 is further guaranteed.

[0046] In this embodiment, if Figure 6 As shown, the driving mechanism includes a driving motor 122, a support shaft 123 and a synchronous belt. The support shaft 123 is installed on the mounting frame 121 through a bearing seat. The driving motor 122 is installed on the mounting frame 121, and the power output end of the driving motor 122 is connected to the support shaft 123. At least two driving pulleys are installed on the support shaft 123. Driven pulleys corresponding to the driving pulleys are also installed at both ends of the mounting frame 121. A synchronous belt is wrapped around the driving pulley and the driven pulley. The synchronous belt is connected to the corresponding clamping unit 100. The driving motor 122 works, thereby driving the support shaft 123 to rotate, thereby causing the driving pulley to rotate. After the driving pulley rotates, it drives the synchronous belt to move. When the synchronous belt moves, it drives the clamping unit 100 to move.

[0047] In this embodiment, if Figure 5 and Figure 6As shown, a pressing block 126 is installed on the sliding plate 101, and the synchronous belt is connected to the corresponding pressing block 126. Further, the pressing block 126 includes a pressing plate 131 and a fixing seat 132. The fixing seat 132 is installed on the mounting frame 121, and the pressing plate 131 is installed on the fixing seat 132. The pressing plate 131 and the fixing seat 132 clamp the belt body of the corresponding synchronous belt. During installation, the fixing seat 132 is detachably installed on the mounting frame 121 by a locking screw, and then the synchronous belt is placed on the fixing seat 132, and then the fixing seat 132 and the pressing plate 131 are locked by screws. Through the clamping of the pressing plate 131 and the fixing seat 132, the synchronous belt and the sliding plate 101 move synchronously. In this embodiment, in order to ensure the reliability of the synchronous belt being clamped by the pressing plate 131 and the fixing seat 132, as shown in FIG. Figure 8 As shown, an anti-slip structure is provided on the clamping surface of the fixed seat 132. Optionally, the anti-slip structure is a plurality of convex teeth 135 arranged at intervals. The convex teeth 135 of the fixed seat 132 are engaged with the convex teeth on the synchronous belt, and the synchronous belt is tightened and cannot slip, thereby ensuring the synchronous movement between the synchronous belt and the sliding plate 101.

[0048] In this embodiment, if Figure 6 and Figure 7As shown, two driving pulleys are installed on the support shaft 123, one of which is equipped with a first synchronous belt 124, and the other is equipped with a second synchronous belt 125, and the pressing block 126 clamps the process belt body 133 of the corresponding synchronous belt.

When in use, when the driving motor 122 rotates forward, the driving support shaft 123 rotates. At this time, the two pressure blocks 126 move toward each other, thereby driving the two clamping units 100 to move toward each other, thereby shortening the distance between the two clamping units 100, and then clamping the silkworm foil. When the silkworm foil needs to be released, the driving motor 122 rotates in the opposite direction, thereby causing the two clamping units 100 to move back to back, thereby increasing the distance between the two clamping units 100, thereby releasing the silkworm foil. In this embodiment, a position sensor 129 for detecting the position of the sliding plate 101 is installed on the top of the mounting frame 121, and in order to facilitate the position sensor 129 to detect the sliding plate 101, a through hole is opened on the mounting frame 121. During the silkworm foil release process, when the position sensor 129 detects the sliding plate 101, it indicates that the sliding plate 101 has returned to the initial position and the silkworm foil release is completed.

[0049] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, the rotating mechanism includes a fixed positioning seat 202, a bearing assembly and a rotating seat 207. In this embodiment, the positioning seat 202 is installed on the ground. Optionally, a base 201 is installed on the ground by pre-buried bolts, and then at least three positioning columns 205 are installed on the base 201. Preferably, the positioning columns 205 are evenly distributed on the same circumference, and the positioning columns 205 are step columns. Then, a through hole matching the small column of the step column is opened on the positioning seat 202, so the positioning seat 202 is placed on the step column. The positioning seat 202 is fixed relative to the base 201 in the circumferential direction, and can be disassembled in the up and down direction, so as to facilitate the assembly of the positioning seat 202. In this embodiment, the bearing assembly includes a bearing outer gear ring 203 and a bearing inner ring 221. The bearing outer gear ring 203 is sleeved on the bearing inner ring 221, and the bearing outer gear ring 203 is installed on the positioning seat 202. The bearing inner ring 221 is connected to the rotating seat 207. The rotating seat 207 is located above the positioning seat 202, and the bearing inner ring 221 can rotate relative to the bearing outer gear ring 203. , a rotating motor 208 is installed on the rotating seat 207, a driving gear 220 is installed at the power output end of the rotating motor 208, the outer side of the bearing outer gear ring 203 is an external gear, the driving gear 220 is meshed with the external gear, a column 210 is installed on the rotating seat 207, and the lifting mechanism is installed on the column 210. In this embodiment, the rotating seat 207, the column 210, and the bearing assembly are all coaxially arranged, so under the action of gravity, the positioning seat 202 can be stably installed on the positioning column 205, and when the rotating motor 208 is working, The driving gear 220 rotates, and since the bearing outer gear ring 203 is stationary, the rotating seat 207 rotates relative to the bearing outer gear ring 203, thereby rotating the column 210, and then driving the silkworm foil clamping assembly 200 to rotate. Furthermore, the teeth on the driving gear 220 and the outer gear are helical teeth, so the driving gear 220 and the outer gear rotate through the helical gears, so that the rotating seat 207 has better balance during the rotation process, and the meshing process of the helical gears is rolling meshing, so the noise is lower and the service life is longer.

[0050] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, the first stroke switch 204 and the second stroke switch 217 for detecting the position of the rotating disk are installed on the positioning seat 202, and the first stroke switch 204 and the second stroke switch 217 are arranged at intervals on the same circumference, and the first stroke switch 204 and the second stroke switch 217 are used to control the rotation angle of the rotating seat 207. Further, a support plate 218 is provided on the rotating seat 207, and the support plate 218 is arranged along the radial direction of the rotating seat 207. The rotating motor 208 is installed on the support plate 218, and the support plate 218 is provided with a through hole for the main shaft of the rotating motor 208 to pass through, and the distance between the outer side of the support plate 218 and the center of the rotating seat 207 is greater than the distance between the first stroke switch 204 and the center of the rotating seat 207. When the first stroke switch 204 detects that the support plate 218 , the rotating motor 208 stops working. Similarly, when the second stroke switch 217 detects the support plate 218, the rotating motor 208 also stops working. Therefore, when in use, after a start command is given to the rotating motor 208, the rotating motor 208 works. When the first stroke switch 204 or the second stroke switch 217 detects the support plate 218, the rotating motor 208 stops working. In the specific implementation process, preferably, the stacking station is located on the front side of the column 210, and the release station is located on the left or right side of the column 210. Therefore, the angle between the stacking station and the release station is 90°, and the initial position of the rotating seat 207 is the position where the second stroke switch 217 just detects the support plate 218. At this time, the clamping unit 100 is located directly above the stacking station.

[0051] In this embodiment, if Figure 3 and Figure 4 As shown, a positioning ring 223 is provided at the bottom of the outer gear ring 203 of the bearing, a positioning step is provided on the positioning seat 202, and the positioning ring 223 is installed on the positioning step, and the outer gear of the outer gear ring 203 of the bearing is located on the positioning seat 202, and the top of the inner ring 221 of the bearing protrudes from the outer gear ring 203 of the bearing. A positioning step is also provided at the bottom of the rotating seat 207, and the top of the inner ring 221 of the bearing is installed in the positioning step of the rotating seat 207, thereby ensuring the stability of the installation of the outer gear ring 203 and the rotating seat 207. Preferably, the outer gear ring 203 of the bearing, the rotating seat 207 and the column 210 are all coaxially arranged, so under the action of gravity, the reliability of the installation of the bearing assembly and the rotating seat 207 can be ensured. In this embodiment, its purpose is to take and place silkworm foil, and the weight of the silkworm foil is relatively light and will not affect the stability of the installation of the column 210. In addition, in the actual process, a counterweight block can be placed on the top of the rotating seat 207 to further prevent the column 210 from tipping over.

[0052] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, the lifting mechanism includes a sliding seat 211, a linear guide assembly 219 and a lifting motor 212. The lifting motor 212 is installed on the sliding seat 211. The linear guide assembly 219 is vertically installed on the column 210. The sliding seat 211 is slidably installed on the linear guide assembly 219. A spur rack 209 is also vertically installed on the column 210. A lifting gear 222 is installed at the power output end of the lifting motor 212. The lifting gear 222 is meshed with the spur rack 209. The cantilever beam 214 is installed on the sliding seat 211, and the cantilever beam 214 is located at the lifting position. On one side of the motor 212, the lifting motor 212 works, thereby driving the lifting gear 222 to roll along the spur rack 209, so that the sliding seat 211 moves along the linear guide assembly 219. The linear guide assembly 219 belongs to the prior art and will not be described in detail. Optionally, the linear guide assembly 219 includes two guide rails arranged at intervals, and the spur rack 209 is located between the two guide rails. A groove that cooperates with the guide rail is opened on the sliding seat 211. Of course, in order to prevent the groove from derailing the guide rail, the groove is set as a dovetail groove, and the guide rail is adapted to the dovetail groove.

[0053] In this embodiment, if Figure 1 and Figure 2 As shown, three mounting brackets 213 are provided on the sliding seat 211 , the mounting bracket 213 is an L-shaped plate, the cantilever beam 214 is a rectangular structure, and the three L-shaped plates are connected to the cantilever beam 214 by screws, thereby ensuring the connection performance between the cantilever beam 214 and the sliding seat 211 .

[0054] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, a first buffer 206 is installed on the rotating seat 207, and the first buffer 206 is located below the sliding seat 211. A top plate 215 is provided on the top of the column 210, and a second buffer 216 is provided on the top plate 215. The second buffer 216 is located above the sliding seat 211. The buffer ends of the buffers are rubber parts, and the connecting ends thereof are screw rods. During the movement of the sliding seat 211, the buffer can prevent the sliding seat 211 from derailing and limit the sliding seat 211. Of course, in actual use, the sliding seat 211 will not contact the buffer, and the buffer mainly plays a role of preventing fooling.

[0055] The working process of the utility model is as follows: at the stacking station, the lifting mechanism moves downward, and when it reaches the specified position, the driving motor 122 rotates forward, and the driving support shaft 123 rotates forward. At this time, under the action of the synchronous belt, the two pressing blocks 126 move toward each other, thereby driving the two clamping units 100 to move toward each other, thereby shortening the distance between the two clamping units 100, and then clamping the silkworm foil. When the clamping unit 100 contacts the silkworm foil, if the second guide slope 110 on the lifting sheet 107 contacts the silkworm foil first, at this time, the silkworm foil is lifted up under the action of the second guide slope 110, and as the clamping unit 100 continues to approach, the silkworm foil enters the clamping groove, thereby completing the clamping of the silkworm foil. If the first guide slope 109 contacts the silkworm foil, as the clamping unit 100 continues to approach, the silkworm foil applies an upward reaction force to the first guide slope 109, and the linear axis is under the action of the reaction force. Move upward, so that the clamping groove can be aligned with the silkworm foil, and finally the silkworm foil enters the clamping groove. Of course, if the silkworm foil and the clamping groove are in an aligned state, the silkworm foil directly enters the clamping groove. After completing the clamping of the silkworm foil, the lifting mechanism moves upward, and after reaching the specified position, the rotating motor 208 works, the rotating seat 207 rotates, and then drives the clamping unit 100 to rotate. When the rotating seat 207 rotates 90°, the first stroke switch 204 detects the support plate 218. At this time, the rotating motor 208 stops working, and then the lifting mechanism moves downward. After reaching the specified position, the driving motor 122 rotates in the opposite direction, so that the two clamping units 100 move back to back, and then the distance between the two clamping units 100 is increased, so that the clamping groove is separated from the silkworm foil, and then the silkworm foil is released. The silkworm foil is placed on the release station, and then the lifting mechanism moves upward, and the lifting mechanism and the rotating seat 207 are reset, and then the next silkworm foil is taken and placed.
